PROBLEM TO BE SOLVED: To protect a see-through area at the plastic board face door of a game machine. SOLUTION: In the board face door 3, a front face member 11 consists of transparent plastic, and a flat face 19 provided at a center part is designated to be the see-through area for seeing through a game area. An acrylic film 12 becoming a surface material is adhered to a part to be the see-through area. Since the surface hardness of acrylic resin is nearly equal to glass, the film 12 is never damaged even when it is rubbed with metal such as a coin. That is, the see-through area is sufficiently prevented from being damaged due to a trick by a player. COPYRIGHT: (C)2006,JPO&NCIPI
